Gentics Flashcards
What is a trait?
When organisms reproduce, traits are passed from parent to offspring.
What does hereditary mean?
The transfer of traits from one generation to another.
What is an allele?
A form of a gene.
What does Purebred?
Carries two copies of the same allel.
What does hybrid ?
Carries two different allels.
What is a dominant allele?
The form of the gene that masks/overpowers the other form of gene.
What is a recessive allele?
The form of the gene that gets masked/overpowered by the dominant allele.
What is a punnet square?
A diagram used by geneticists to determine the probability (chance) of an offspring having a particular phenotype
What does homozygous mean?
The same in relation to alleles.
What does heterozygous mean?
Different in relation to alleles.
What is a genotype?
The genetic makeup of an organism.
What is a phenotype?
The appearance of an organism based on phenotype and outside factors.
What does a gene do?
Genes determine a trait.
What is a chromosome?
Something that contains DNA.
What does the law of incomplete dominance state?
One gene does not completely mask the other.
The heterozygous genotype results in an intermediate phenotype.
